Why does the flu always spread more in the winter?

We're coming into flu season the same way we do every year -- the colder it gets the more of us seem to get sick. So why is that? Why is it that the flu seems to spread so fast in the fall and winter months? It's really very simple: the flu virus likes cooler temperatures and lower humidity.

So knowing that, there are a couple things you can do to help slow the spread and minimize your chances of getting sick:

• Keep room thermostats set at 68º F or higher.
• Try to keep room humidity at 50% or greater.

Plus, of course, take care of yourself!
